The answer will be answered immediately.nLooking at the gold color, the higher the purity of the gold jewelry, the deeper the color; 2. Look at the gold weight, the proportion of gold is 19.32, which is more important than metal such as silver, copper, lead, zinc, aluminum. Low hardness, shallow marks with nails, teeth bite can leave tooth marks, golden island, high -colored gold jewelry is lower than the soft color, the more copper, the harder, the more the bending method can test the hardness. Pure gold can also be tested. Soft, easy to bend, the lower the purity, the less likely to bend. The gold content is not less than 999.nFirst, when you can bite your teeth, when you watch TV, you must have seen such a lens. It is to bite the authenticity of gold with your teeth, because the texture of gold is relatively soft, and the tooth print will appear with the teeth. Tooth printing is definitely a fake gold. Second, use fire to say that "real gold is not afraid of fire", that is to say, really gold is not afraid of high temperature. The melting point of gold is more than 1,000 degrees. You can use fire to burn gold. If the color change or the melting phenomenon is definitely a fake gold. Third, when listening to the sound, when the gold is tapped, the gold will really make a sound of "hits, click", and the fake golden sound will be more crispy, generally the sound of "Dangdang". Fourth, ceramic scratch test method uses unlawish ceramics. If you use ceramics to draw gold products, if it is a black scratch, it means that the product is not gold, and if it is a golden scratch, it proves that the product is gold. Fifth, magnet testing is a simple test, but it is not a sufficient proof to prove whether it is real gold. You can find a powerful magnet for testing. Gold is not a magnetic metal. If the product is attracted by magnets, it is enough to prove that this product is not gold. However, it cannot prove that it is gold because the product does not respond to magnets, because there are many non -magnetic metals.nI hope my answer can help you and wish you a happy life.nMore 2nBleak
Many people don't know how to distinguish the authenticity of gold. Let's take a look at how to distinguish it! 01 The color This can generally distinguish pure gold, K gold, real gold and fake gold according to the different gloss and color of the gold. That is, gold is better yellow (yellow -red), and the color is more than 95%; the positive yellow color is about 80%; the blue and yellow color is about 70%; the yellow color is slightly gray and the color is about 50%. Therefore, there is a formula for "seven green eight yellow, yellow nine five red, yellow leucorrhea ash pairs of gold". For long -term gold jewelry, there will be a saying that "copper turns green, silver turns black, and gold will never change color". 02 The golden . As the saying goes, real gold is not afraid of fire, even if the gold is burned red, it is still the glittering golden light after cooling. 03 This label The domestic gold jewelry is to be used as a kill. It indicates that 24K represents a purity of more than 99.6%and indicates that the purity is above 75%. 04 In listening to the sound This will make the pure gold jewelry on the ground, and it will make a click. The fake or bad gold falls on the ground, and it will make a dwelling sound, and it will be beating after landing. 05 Chemical identification The gold jewelry is placed in an alcohol solution, and the filter paper is soaked in the solution. At this time, the filter paper will become gray purple. Drops of bromine -A are on the filter paper. If it is really golden filter paper, it will turn white! 06 r The proportion of gold is 19.3g/cm3. The relationship between the color and the proportion is relatively large. When the proportion is close to 19.3, the higher the pure gold. When the proportion is 18.5, 95%gold contains gold, and 90%of gold is contained at 17.8, and so on. As long as the proportion is measured, you can know the color of the jewelry, but in general, you can feel it in your hands. If you have a slightly heavy feeling, you can perceive it, because other metals with the same weight, such as silver, copper, tin, lead and other weights, etc. are different.

Many people don't know how to distinguish the authenticity of gold. Let's take a look at how to distinguish it!
01
The color
This can generally distinguish pure gold, K gold, real gold and fake gold according to the different gloss and color of the gold. That is, gold is better yellow (yellow -red), and the color is more than 95%; the positive yellow color is about 80%; the blue and yellow color is about 70%; the yellow color is slightly gray and the color is about 50%.

02
The golden
. As the saying goes, real gold is not afraid of fire, even if the gold is burned red, it is still the glittering golden light after cooling.
03
This label
The domestic gold jewelry is to be used as a kill. It indicates that 24K represents a purity of more than 99.6%and indicates that the purity is above 75%.
04
In listening to the sound
This will make the pure gold jewelry on the ground, and it will make a click. The fake or bad gold falls on the ground, and it will make a dwelling sound, and it will be beating after landing.
05
Chemical identification
The gold jewelry is placed in an alcohol solution, and the filter paper is soaked in the solution. At this time, the filter paper will become gray purple. Drops of bromine -A are on the filter paper. If it is really golden filter paper, it will turn white!
